I live in Wittman, Az in desert conditions. I have just bought some former horse property, all dirt (clay type). There are 2 easements. I want to plant a blackberry hedge on my side so I can limit access to my living area. What should I do to prepare the ground for this planting? Should I provide a support trellis? I believe I have until spring before I plant, so I have time to develop the soil. I plan on eating/canning the fruit. Thanks.

For hedge plantings, I would probably go with erect varieties rather than the trailing types (which would benefit from a trellis), though the choice is yours. They should also be planted about 2-4 feet apart for an ideal hedge. These articles should help as well: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/how-to-improve-clay-soil.htm
